To allwhomitmayconcem:

' Be it known vthat I, WILLIAM'VH. Mo- LAUGHLIN, a citizen'of the" United States, residing atI-Iartford, in the county'of Hartford and State of'KConnecticut, have in vented certain new and useful Improvements in Traction Devices, of which the following is alsp'ecification.

This inventionurelates to. clamps or attachingmeans of the spring clip, or clasp type, preferably of integral vconstruction to i be sprung overland across the, felly of. ,an

automobile wheel, and to'be held against I displacement by 'cooperatinglrmeans carried by "said felly, and is more particularly designed for use with the wheels" ofkthe lighterclasses of pleasure and business automobiles. The object of. this, invention is. to" provide a resilient metal clip orQclam'p having re-' silient hooks to receive the terminal links of an anti-skidding chain. and which maybe easily and quicklyiattached f and detached without. the use of any tools,- and which need not employ any screws or similar fastenings to be manipulated each entimewthemclip is applied or removed; I, i In the accompany ng draw-ingsz 7 1 Figure lrepresents "a .vlewin side elevation of a segment of a wheel with devices embodying my invention applied thereto ';Fig. 2, a sectional v1ew;on.the "line 2-2 .ofFig. 1; i

clip alone.

Referring" now indetail tovthe drawings,

A represents the pneumatic. tire of the wheel,

B the rim, C the felly, and D the anti-skid-v ding chain provided on each end with two' rings or round links E. V Y

The felly C is provided at intervals with pairs of nails or studs ;1 having split points ,'App1ication,filed. July 1a, 1917.,,Seria1-'N0. 180,328.

vided with a short lip 2 presentedtoward Spring clips orf clampsB ofelojngated ushape and preferably stamped or formed from a single piece of sheetmetal and provided with slots 4: in'their sidesareadapted to be forced over said felly C, each side engaging and riding outwardly onthe inclined face of the head of the ,:corresponding.nail 1 until the edge of its slot 4 passesflbeyond the edge of the lip 2, when it will snap in- Wardly against Itheside of the felly.

The bridge of the clipis to bemade slightly longer than theewi'dth' 0f.. the .felly 1t 1s lntended to be applied; to, and-the sides Wlll be drawn in slightly toward eachfother' to' allow the clip as a, whole to be slightly deformed, as'stated, to get the dge'sfdfiits slotsvt' beyond the lips 2, when-it will spring back 1nto normal'shape, drawing its sides toward the innerperiphery" of the ,felly so that the material of the sides of the clip adjacent'the edges jof' the slots 4! will be drawn between the sides of the The sides of the'clip orclamp ,31 are bent outwardly back on themselves, to form hooks 5, the end portions of .wh-ichearere- V ,fell'y Qand the lips 2 of the respective'nails 1L duced in thickness, increasing. their ,resilii ency at, this point; The-end, portions of these hooks ,5 will be normallyfheld, by their own resiliency,' againsti the fa'dj acent faces of thesides of the'clip;

f' In practice, vafter these clipshavebeen snappedon as above, ringsE attached tolthe ends of an anti skidding chain D and forming termlnal links-thereofiwill be snapped into the hooks 5 of each of'saidclips.

f-The material of said hooks 5 may be cut away as at 6, as shown, in order to better receive andposition the cooperating rings 13 of the anti-skidding chainsD."

vTwo such rlngs E are shown attached to each endof each chain to allow-them to be adjusted in length to suit the cross-sectional measurementsof the tire, rim and felly.

The inner face of the bridge of the clip or clamp 3 may be provided with a rubber treated textile lining F, as shown, to prevent marring of the inner peripheral face of the felly C.

To remove the clips it is simply necessary, in each instance, to unhook one end of the anti-skidding chain and pull it laterally of the wheel, thus pulling the side of the clip 3,

to which it is still hooked, away from the 3, ;when its resiliency will force it free from the, felly C andthe other lip 2. V y Having thus described my inventiom'what I claim as new and desire to secure by Letters Patent is:- l r i 1. A resilient clipadapted to have positive 7 engagement with' a wheel felly and provided with a=-portionin arranged position extend-'7 in across thevinner peripheral" face of the fe y' and with side portions having means to receive respectively the terminal portions of an anti-skid 'or traction element, each side portion being provided with a face to V engage a lug, the engaged face of which lies substantially in a plane transverse of the wheel, whereb the resilient clip in applied relation willv e held firmly against movement radially as a wholetoward the hub of the wheel, but may be easily and quickly reportions;

moved by a lateral pull onone: ofthe side 4 v 12.'A clip adapted to have positive-engagement' with a wheel 'felly and provided with a'portion in arranged position extend ing' across the inner peripheral face of the felly and with resilient side portions having means. to receive respectively the terminal portions of an anti-skid or traction element; each side portionbeing provided with a face to engage a lug, the engaged face of which lies substantially i'na plane transverse of thei felly, whereby the clipj in applied relation will be held firmly against movement radi i ally as a whole toward the hub of the wheel, but may be easily and quickly removed'by a lateral pull on one of the side portions.

, mounted thereinland projecting from the portions being provided respectivel respective lateral faces thereof, in combination with a resilient clip bridging said felly V means to receive the terminal portions of an anti-skid or traction element at points radially from the hub beyond said project ing parts, and being cut out to receive and be sprung oversaid projecting parts to hold 7 spokes of thewheel andagainstradialmovesaid clip against creeping movement rela 'tively to the felly between the adj acent side of the fell 0 and'free of the 1ip2, as s illustrated in, ig

ment towardthe hub of the wheel, the re I siliency ofthe clip permitting its expeditious l removal simply by a lateral pull on one of. 'the side portions resulting in dlsengaging it from its'respective projectiongfg 4;. A part having two faces and headed studs projecting from each of said faces'and provided with lips, in combination with an inte ral resilient metal cli' hav'in ortions adapted to engage said'faces adjacent said;

studs, said portions being'adapted to receive said studs and engage the lips thereof and element. A part havingtwo faces and headed provided withmeans to receive an additional studs projectingfrom said faces respectively and having their axes'substantiallyl in alinement and provided with lips, combination with an integral resilient metal clip having I two slotted portions adapted to engage vsaid faces and receive said studs and to fit between said lips respectively and the adja cent portions of said faces, said portions being providedwith means to receive an additional element. x v 7/ 6JA wheel felly,'in"combination witha clip having resilient side portions engaging the opposite side faces-ofthe f elly, said i felly and side portions being provided with positive interengaging means, the 'saidside portions'of said plate being providedflwith means to removably' receive the respective termlnaljportions of a tract on elementat 7 points radially from the hubbeyond said'interengaging means, and 'a tractiondevice thus connected to said side portions of the v I clip, th'e'device as a .whole'being removable 3.
